I want to know if I have this correct because I am confused. I think this is x-linked recessive is that right since it can fall into this category 1.Usually more males than females are affected.2. Affected sons are usually born to unaffected mothers;thus, the trait skips generations.3. Approximately half of a carrier (heterozygous) mother’ssons are affected.4. Never passed from father to son.5. All daughters of affected fathers are carriers.

1. Cannot be x-linked recessive: in order to have an affected female progeny, you need to have heterozygous carrier mother AND father. That means that father would be affected too (single X chromosome).2. Thus, it's an autosomal (see above) recessive (since neither parent affected, it cannot be dominant).

Tip: in pedigree analysis you must identify what it cannot possibly be and then you will be left with only possibility.
